Argentine Navy: Submarine's battery short-circuited before it went missing

The battery on an Argentine submarine that went missing earlier this
month short-circuited shortly before the vessel's last communication,
the country's navy said Monday.

The submarine's captain had informed the navy that water had entered the
vessel while it was charging its battery, causing a short circuit, navy
spokesman Enrique Balbi told reporters today. The ARA San Juan was last
heard from on Nov. 15.
